Is there a standard procedure for assessing and providing assistive devices for people with neuro-disabling conditions in United Kingdom? A nation-wide survey.

BACKGROUND: Assistive devices are currently provided to people with neuro-disabling conditions to promote or maintain independence in activities of daily living. However, it is unclear whether assessment procedures performed by health care professionals to guide the provision of assistive devices are standardized. OBJECTIVE: To explore the assessment and service-delivery processes of assistive devices for people with multiple sclerosis, cerebrovascular disease and Parkinson's disease experiencing physical disability by health care professionals in the United Kingdom. METHODS: A survey was conducted among UK health care professionals working with people with neuro-disabling conditions. Descriptive and content analyses were used to code survey data. RESULTS: In total, 231 health care professionals completed the survey: 93 occupational therapists, 136 physiotherapists and 2 assistant practitioners. Less than half of the respondents (46%) reported use of local, national, or combined guidelines when assessing a service user's suitability or need for assistive devices. When guidelines were used, they were not consistent and not specifically for assistive devices. The respondents stated that when users were allocated small and portable assistive devices, they were supplied within four weeks. This period increased for large equipment, major home adaptions or if external specialist services and/or funding was needed. CONCLUSIONS: Standardized operating procedures for assistive device provision are not being carried out within the UK. Variable access to assistive devices supplied by the state indicates inequity across regions. Future research should explore potential benefits of developing standardized assessment procedures for the provision of assistive devices and devise methods to reduce current variability in service delivery.

Orientation and verbal fluency in the English Longitudinal Study of Ageing: modifiable risk factors for falls?

OBJECTIVES: To determine the relationship between falls and deficits in specific cognitive domains in older adults. DESIGN: An analysis of the English Longitudinal Study of Ageing (ELSA) cohort. SETTING: United Kingdom community-based. PARTICIPANTS: 5197 community-dwelling older adults recruited to a prospective longitudinal cohort study. MEASUREMENTS: Data on the occurrence of falls and number of falls, which occurred during a 12-month follow-up period, were assessed against the specific cognitive domains of memory, numeracy skills, and executive function. Binomial logistic regression was performed to evaluate the association between each cognitive domain and the dichotomous outcome of falls in the preceding 12 months using unadjusted and adjusted models. RESULTS: Of the 5197 participants included in the analysis, 1308 (25%) reported a fall in the preceding 12 months. There was no significant association between the occurrence of a fall and specific forms of cognitive dysfunction after adjusting for self-reported hearing, self-reported eyesight, and functional performance. After adjustment, only orientation (odds ratio [OR]: 0.80; 95% confidence intervals [CI]: 0.65-0.98, p = 0.03) and verbal fluency (adjusted OR: 0.98; 95% CI: 0.96-1.00; p = 0.05) remained significant for predicting recurrent falls. CONCLUSIONS: The cognitive phenotype rather than cognitive impairment per se may predict future falls in those presenting with more than one fall.

Factors predicting incidence of post-operative delirium in older people following hip fracture surgery: a systematic review and meta-analysis.

OBJECTIVE: Delirium is one of the most common complications following hip fracture surgery in older people. This study identified pre- and peri-operative factors associated with the development of post-operative delirium following hip fracture surgery. METHODS: Published and unpublished literature were searched to identify all evidence reporting variables on patient characteristics, on-admission, intra-operative and post-operative management assessing incident delirium in older people following hip fracture surgery. Pooled odds ratio (OR) and mean difference of those who experienced delirium compared to those who did not were calculated for each variable. Evidence was assessed using the Downs and Black appraisal tool and interpreted using the GRADE approach. RESULTS: A total of 6704 people (2090 people with post-operative delirium) from 32 studies were analysed. There was moderate evidence of nearly a two-times greater probability of post-operative delirium for those aged 80 years and over (OR: 1.77; 95% CI: 1.09, 2.87), whether patients lived in a care institution pre-admission (OR: 2.65; 95% CI: 1.79, 3.92), and a six-times greater probability of developing post-operative delirium with a pre-admission diagnosis of dementia (OR: 6.07, 95% CI: 4.84, 7.62). There was no association with intra-operative variables and probability of delirium. CONCLUSION: Clinicians treating people with a hip fracture should be vigilant towards post-operative delirium if their patients are older, have pre-existing cognitive impairment and poorer overall general health. This is also the case for those who experience post-operative complications such as pneumonia or a urinary tract infection. Copyright © 2017 John Wiley & Sons, Ltd.

Tracking EEG changes in response to alpha and beta binaural beats.

A binaural beat can be produced by presenting two tones of a differing frequency, one to each ear. Such auditory stimulation has been suggested to influence behaviour and cognition via the process of cortical entrainment. However, research so far has only shown the frequency following responses in the traditional EEG frequency ranges of delta, theta and gamma. Hence a primary aim of this research was to ascertain whether it would be possible to produce clear changes in the EEG in either the alpha or beta frequency ranges. Such changes, if possible, would have a number of important implications as well as potential applications. A secondary goal was to track any observable changes in the EEG throughout the entrainment epoch to gain some insight into the nature of the entrainment effects on any changes in an effort to identify more effective entrainment regimes. Twenty two healthy participants were recruited and randomly allocated to one of two groups, each of which was exposed to a distinct binaural beat frequency for ten 1-minute epochs. The first group listened to an alpha binaural beat of 10 Hz and the second to a beta binaural beat of 20 Hz. EEG was recorded from the left and right temporal regions during pre-exposure baselines, stimulus exposure epochs and post-exposure baselines. Analysis of changes in broad-band and narrow-band amplitudes, and frequency showed no effect of binaural beat frequency eliciting a frequency following effect in the EEG. Possible mediating factors are discussed and a number of recommendations are made regarding future studies, exploring entrainment effects from a binaural beat presentation.
